Abstract: An automatic revolver has a body, a barrel arranged in the body and having an inner passage provided with a thread-like formation, an ammunition-containing element from which a bullet is displaced into the barrel, the barrel being turnable relative to the body so that when a bullet passes through the barrel and rotates in one direction, the barrels is rotated by a reactive moment in an opposite direction.

Abstract: A firing abort and hang fire safety system for a small or medium caliber multi-barrel automatic weapon includes a device to immobilize the revolving assembly (100) of the weapon in rotation. This device includes a shock-absorbing device mounted coaxially to the revolving unit of the weapon, a control device integral in rotation with the revolving unit and able to translate, further to the misfire of a round of ammunition or to the activation of an external control, to compress the shock-absorbing means device and absorb the rotational kinetic energy of the revolving unit of the weapon. The backspring of the shock-absorbing means device thereafter causing the revolving unit of the weapon to rotate in the opposite direction before stopping.

Abstract: A cartridge soft feed mechanism for presenting the cartridge to the chamber of a gun in such a way that the axis of the cartridge experiences no lateral or angular movement during chambering. The cartridge is telescoped into the chamber without ramping, reducing the probability of damage to the cartridge and reducing the chance of a chambering stoppage. The barrel is moved to a position and at such an angle during chambering that the cartridge is moved directly forward into the chamber, and then the barrel with the cartridge is moved into alignment with the moveable bolt for firing.

Abstract: The present invention relates to a regenerative hydraulic starter/speed regulator system for providing initial rotation and acceleration of a rotatable barrel cluster of a gun gas driven Gatling gun, and for controlling the speed of the barrel cluster during the firing of the gun. The hydraulic system includes a high pressure accumulator for containing a supply of pressurized hydraulic fluid. A hydraulic motor/pump unit is connected to either drive or be driven by the barrel cluster, depending on whether the motor/pump unit is operated in either the motoring or pumping mode. Initially, a servo mechanism operates the motor/pump unit in the motoring mode wherein pressurized fluid from the accumulator is supplied to the motor/pump unit to initially rotate and accelerate the barrel cluster in a firing direction until the rotation of the barrel cluster is sustained by the gun gas drive unit.

Abstract: A gun system is provided which includes a Gatling type gun having a housing with a ring gear, a rotor with a cluster of gun barrels, a gun gas drive mechanism with a cylinder, a piston, and a crank with a pinion meshed with the ring gear.

Abstract: A gun system is provided which includes a Gatling type gun; a barrel cluster having a torque assist device and coupled to a hydraulic starting subsystem to provide initial acceleration, rotational velocity control, braking and reverse clearing of the gun; and a gun gas drive to provide steady-state energy for rotation of the barrel cluster.

Abstract: A multiple barrel gun for firing projectiles at an extremely high rate of fire, in the form of a dense cloud of projectiles. In one embodiment, hundreds of gun barrels are rapidly rotated about a fewer number of fixed firing stations. As each group of barrels approach the fixed stations, cartridges are radially fed to the barrels, and the group of barrels are concurrently fired when they become aligned with the stations. During each complete revolution of the multiple barrel gun, all of the gun barrels are successively fired in groups a number of times corresponding to the number of firing stations. The total fire power of the gun for each revolution is accordingly equal to the number of barrels times the number of firing stations.

Abstract: A Gatling gun wherein a fluid under pressure drives a plurality of double acting pistons to respectively reciprocate each of the gun bolts in the rotor. The gun bolts have respective cam followers which operate in a stationary helical cam to cause rotation of the rotor.
